What is a Sequence?
highA sequence is an ordered list of numbers, objects, or quantities written according to a rule or pattern.
Always write the term position along with the term value when solving missing-term or nth-term questions.
Explicit (Direct) Rule for a Sequence
highAn explicit rule gives the value of any term directly using its position number n.
Before substituting, write what n means: n = required position number.
Recursive Rule
highA recursive rule defines each term of a sequence using one or more previous terms, along with a starting term.
In recursive questions, mention both the first term and the rule for getting the next term.
